摘要：

Being motivated hy recent experimental data on YBaCuO, we calculate the de resistivity rho in the spin-gap state of the charge-spin-separated t-J model using a massive gauge theory ef holons and spinons. The result shows that rho(T) deviates downward from the T-linear behavior below the spin-gap onset temperature T* as rho(T) proportional to T{1 - c(T* - T)(d)}, where the mean field value of d is 1/2. To achieve smooth deviation from the T-linear behavior, d > 1 is required. The deviation reduces with increasing hole doping.
